[The Fields Say:]

HaShem founded the earth with wisdom;

He established the heavens with understanding

(Mishlei 3:19)

HaShem called upon wisdom by imbuing it with the power to create heaven and earth.  By understanding "He created the heavens," for, behold, the heavenly bodies have not strayed from their paths since the day they were created.

The field is a metaphor for man. If unused, wisdom remains a capability that is wasted. Understanding is the mental exertion that processes facts and draws new knowledge from them.  Wisdom is mentioned first, for it pertains to the beginning stage, then comes understanding.  For where there is no knowledge, there is no understanding; and when there is no understanding, there is no knowledge. We should seek to nurture and grow the spark of wisdom that G-d has given.
